Benchmark U.S. crude dropped 66 cents to $48.22 per barrel in electronic trading on the New York Mercantile Exchange

Global stocks fell Tuesday as jittery investors awaited the U.S. Federal Reserve’s decision on interest rates and worried about Britain’s vote on whether to leave the European Union.

KEEPING SCORE: France’s CAC-40 was down 1.3 percent to 4,171 and Germany’s DAX retreated 0.6 percent to 9,599. London’s FTSE 100 declined 1.2 percent to 5,970. In a sign that investors are seeking safe havens, the yield on Germany’s 10-year bond fell below zero for the first time ever. The bond yields, which drop as bond prices rise, are also under pressure from central banks’ ultra-loose monetary policy.

Wall Street looked set for more declines, with futures for the Dow Jones industrial average and the Standard & Poor’s 500 both down 0.1 percent.

FED WATCH: The Fed had been expected to raise interest rates but now appears likely to wait and see how economic changes develop. The central bank’s two-day meeting starts Tuesday, with a decision on interest rates Wednesday. Last month, many investors were betting that the Fed would hike rates, but the most recent monthly U.S. jobs reports were weaker than expected, putting a damper on those expectations.

BREXIT: Stocks are under pressure from uncertainty about whether British voters will choose to leave the European Union in a June 23 referendum. Polls show the vote could go either way and investors are starting to worry about the consequences. A British exit from the EU, known informally as Brexit, would likely hurt the British economy most and destabilize the rest of Europe. The repercussions, however, are not clear and investors are reacting to the general uncertainty over the situation.

CHINA WEAKNESS: Factory output and investment in May were weaker than expected, hurt by slow foreign and domestic demand. Industrial production held steady at 6 percent. Growth in investment in factories and other fixed assets weakened to 9.6 percent in the January-May period from 10.5 percent for the four months through April. “Momentum appears to be stalling after a solid start to 2016,” said Mizuho Bank in a report.

ENERGY: Benchmark U.S. crude dropped 66 cents to $48.22 per barrel in electronic trading on the New York Mercantile Exchange after the International Energy Agency said that prices were unlikely to rise significantly in the future due to large inventories and production increases. Brent crude, used to price international oils, fell 66 cents to $49.69 per barrel in London.

CURRENCY: The dollar declined to 105.87 yen from Monday’s 105.96 yen. The euro edged down to $1.1223 from $1.1293.
